EMPIRICAL RESEARCH

• Empirical research is research using empirical evidence. It is a way of gaining knowledge by means of direct and indirect observation or experience. Empiricism values such research more than other kinds. Empirical evidence (the record of one's direct observations or experiences) can be analyzed quantitatively or qualitatively. .

• Through quantifying the evidence or making sense of it in qualitative form, a researcher can answer empirical questions, which should be clearly defined answerable with the evidence collected (usually called data). Research design varies by field and by the question being investigated. Many researchers combine qualitative and quantitative forms of analysis to better answer questions which cannot be studied in laboratory settings, particularly in the social sciences and in education

• In some fields, quantitative research may begin with a research question (e. g. , "Does listening to vocal music during the learning of a word list have an effect on later memory for these words? ") which is tested through experimentation. Usually, a researcher has a certain theory regarding the topic under investigation. Based on this theory some statements, or hypotheses, will be proposed (e. g. , "Listening to vocal music has a negative effect on learning a word list. ").

• From these hypotheses predictions about specific events are derived (e. g. , "People who study a word list while listening to vocal music will remember fewer words on a later memory test than people who study a word list in silence. "). These predictions can then be tested with a suitable experiment. Depending on the outcomes of the experiment, theory on which the hypotheses and predictions were based will be supported or not, or may need to be modified and then subjected to further testing.

Empirical cycle • A. D. de Groot's empirical cycle • Observation: The collecting and organization of empirical facts; • • Forming hypothesis. Induction: Formulating hypothesis. Deduction: Deducting consequences of hypothesis as testable predictions. Testing: Testing the hypothesis with new empirical material. Evaluation: Evaluating the outcome of testing
